Reciprocating Positive Displacement Pumps Allow for Hassle-free Pumping and Processing in Wastewater Treatment Plants Although the design of wastewater treatment plants has evolved, basic pump requirements have remained constant. Positive displacement pumps, like double disc pumps, are more relevant than ever in a variety of applications for longevity and pumping success. Learn how reciprocating positive displacement pumps operate with relative ease. Take a deeper look into how these pumps can be used in: Varying clarification processes Secondary treatment technologies Thickened sludge and ..read more

Moving towards becoming more homeland dependent, the United States government has set up the Build America, Buy America Act (BABAA) that requires that all federal agencies, including FEMA, ensure that no federal financial assistance for ‘infrastructure’ projects is provided unless all the iron, steel and manufactured products and construction materials used in the projects are produced in the United States.  By taking the BABA initiative into account, the push for domestic suppliers has never been stronger. With that said, PVP is proud to serve as a BABA compliant manufacturer within the ..read more

Before making a big purchase, no matter what it is, doing due diligence and really looking at and understanding what something will cost may save you quite a bit of money in the long run. For things like large pieces of equipment, including pumps, knowing the total lifecycle cost prior to purchase is extremely important for that very reason. What is Lifecycle Cost and How Does it Relate to Pumps? Lifecycle cost is the total ‘lifetime’ cost to purchase, install, operate, maintain, and dispose of a piece of equipment. Pumps generally do not stand on their own. Although they may be purchased sepa ..read more

Running a pump while it is dry is usually one of the worst things you can do to it. Dry running occurs when a pump runs without sufficient liquid flowing through it. When this happens, a surge in pressure, flow or overheating occurs. Elements within the pump casing seize together. This triggers shock waves inside the pump which cause significant damage to the pump, resulting in total failure. This then creates a domino effect, leading to the possibility of millions of dollars being lost annually through replacement costs for damaged equipment, as well as loss in revenue due to the pump bei ..read more

Skimming scum off the top of a clarifier water surface and putting it in a scum collection box is a dirty job. Anything that floats, like plastics or grease, rises to the surface during the wastewater clarification process and needs to be removed. Eradicating scum from a wet well in the traditional way is truly a messy job. Scum Removal in the Traditional Way During traditional scum removal processes, wet wells are outfitted with a level control system. This system starts and stops the pumps in the well as the fluid in the well rises and falls. As this happens, the layer of scum that has been ..read more
